In late August, all PRISM systems, including red, will be upgraded from CentOS 6 to CentOS 7. Are you interested in evaluating CentOS 7 now? If so, ssh to our test system, red7. In order to use red7 externally, you must ssh to red first. red7 will only be available during the duration of the testing period. Please send any feedback to tech@eecs.yorku.ca.
